Abstract: 711,359. Delivery apparatus; feeding sheets. ROCKWELL, C. L., GANTENBEIN, R. P., ASTON, G. G., and ADAMS, R. June 18, 1951, No. 14399/51. Class 100 (1) A newspaper stuffing machine comprises a guideway through which folded outer newspaper sections are delivered, mechanism adjacent the inner end of the guideway for opening the first newspaper section and holding it open to receive an insert, a second guideway through which insert newspaper sections are delivered, mechanism adjacent the inner end of the second guideway for lifting the bottom edge of an insert and guiding it to rollers for feeding it into the opened outer sections; and mechanism for moving the outer section with the inserted section therein away from the first guideway. As shown, Fig. 1, the machine comprises a delivery shoot 12 holding newspaper sections A which are to be stuffed into the sections B in a second shoot 13. For removing the sheets A singly from the shoot 12 there is provided an oscillating cam roller 18 which is moved initially in a clockwise direction so as to lift the bottom of a folded section clear of a lip 15 on the shoot 12. This bottom portion is taken up by a hook 23 on a " pick-up " cam 20 and fed between the cam 20 and a pressure roller 24 under a fixed guide 70. As the section is being fed between the cam 20 and roller 24 the cam roller 18 moves in an anticlockwise direction with the movement of the section. This is achieved by providing a gear on the shaft of the roller 18 which meshes with a rack oscillated backwards and forwards by a disc part on the shaft 22 of the cam 20, Figs. 8 and 9 (not shown). The section A' is then fed by rollers 38, 39 into an opened section of the newspaper B and the two sections are then fed to a receiver by a second " pick-up " cam 79 and pressure roller 80. The newspaper section B is opened by an oscillating arm 45, Fig. 14, oscillated by a link 49 attached to a driven cam 51. The arm 45 is pivoted at 46 and carries a hinged extension 45' normally held in alignment with the arm 45 by a spring 64 and having a rubber engaging element 48 at its end. Rotation of the cam 51 causes the arms 45, 45<SP>1</SP> to rotate in an anti-clockwise direction the element 48 engaging one edge of the newspaper section and causing it to buckle. As the cam further rotates the lower end arm 53 carrying a wedge 56 at its upper end rides into a slot 57 in the cam 51 and under the action of a spring 55 rotates anticlockwise about its pivot 54 to insert the wedge 56 between the fold of the section B<SP>1</SP>. At the same time a bell crank 58 pivoted on the wedge 56 is rotated in an anticlockwise direction, so as to force the folds apart by the action of one of its arms 60 upon the side frame 11 of the machine. During this time a press bar 78 mounted on an arm 76 pivoted at 77 is pressed against the leading newspaper section B by the action of a cam 75, Fig. 3 (not shown). During the latter part of the anti-clockwise travel of the arm 45 the extension 45<SP>1</SP> pivots about its hinge to release the edge of the folded section owing to the action of a pin 80 thereon which rides up a cam surface 81. The bar 78 is then moved away from the section and the edge released by the arm 45 is engaged by a rotating element 61 which draws the edge over a roller 63 on an arbor 68. At this time the sheet A<SP>1</SP> is inserted between the folds of the section B. Continued rotation of the element 61 causes the engaged ,dge of the section to be released after the insertion of the section A<SP>1</SP> and the two sections are then taken up by the " pick-up " cam 79.
